UNITED STATES PATENT OFFICE.

\ GEORGE M. BRILL, OF PHILADELPHIA, PENNSYLVANIA.

CAR-BRAKE.

SPECIFICATION forming part of Letters Patent No. 286,773, dated October 16, 188?.

Application filed February 2, 1883. (No model.)

To all whmn it may concern.-

Be it known that I, GEORGE M. BRILL, a citizen of the United States, residing in the city and county of Philadelphia, State of Penn-- car-truck, and B represents one of the brakeshoes, the connected rod 0 of which is pivoted to the lever D, to which also is pivoted the connecting-rod G of the opposite brake-shoe.

E represents the rods, which are pivoted to the lever D and extend toward the platforms of the cars for operating the brakes, which several features are well known. The lever D is pivoted to a hanger, F, which depends from and is loosely attached to swinging links H, which depend from the truck, and are per mitted to swing toward the front and rear of the car, the hanger and lever'being connected by the pivotal bolt G.

It will be seen that when the brakes are ap plied the brake-shoes are forced against the car-wheels, as usual. Should, however, there be any inequality of action'of said shoes, due either to the irregular wear of parts, the overloading of the car at one end, or the inclination thereof at either end when running on ascending or descending grades, whereby the greater or entire part of service. of the brakes is rendered by one shoe or one pair of shoes, the lever D is caused to move with the hangers as one, owing to the links H, and obtains, as it were, a new pivotal point, so as to compensate for the inequality of action of the opposite brake-shoes, and cause the same to act simultaneously and uniformly on the wheels to which the brakes are applied.

Hav ing thus described my invention, what I claim as new, and 'desire to secure by Letters Patent, is-

1. The brake-lever D and the links H, in combination with a hanger which depends from said links and has'said lever connected with it, substantially as and for the purpose set forth.

2. The brake-lever D and the links H, in combination with a hanger and pivotal bolt, said hanger depending from the links, and said bolt connecting the hanger and lever, substantially as and for the purpose set forth.
